Did you debug the UI on web mode? Scrolling the upgrades just flips between the top and bottom, meaning once trophy upgrades are added to the list, upgrades like Triage are impossible to choose since they are shunted down off the screen.
Ahaaa, made you make an update! Had the same issue, been playing for 4 hours, hoped that numbers would work but tapping 6 did nothing. happy its fixed.
But the game is actually very fun and plays great. Gj.
